There's a reason Gisele Bundchen is one of the most famous supermodels in the world. And that reason was abundantly clear on Feb. 8, when she stepped out in Hawaii wearing a skimpy black bikini -- just two months after giving birth to her second child.

The Brazilian-born stunner, 32, showed off her sexy, slim post-baby body in a halter-style two-piece with side-tie bottoms. Her eyes were obscured by the brim of a floppy straw hat, but she couldn't hide her smile as she walked through the sunny resort.

Bundchen -- who arrived in Hawaii via private jet on Feb. 7 with husband Tom Brady, son Benjamin, 3, and daughter Vivian Lake, 2 months -- has never been shy about showing off her world famous body, even while pregnant. In November, just a few weeks before giving birth, she flaunted her bump in a leopard-print bikini while on vacation in Miami Beach.

During a 2010 interview with Vogue, the former Victoria's Secret Angel explained the secret behind her ability to bounce back so quickly after baby. She said that she "gained only 30 pounds" while carrying her son in 2009 and was active for almost the entire nine months.

"I did kung fu up until two weeks before Benjamin was born, and yoga three days a week," she told the mag, adding that she was "mindful" of her diet, too. "I think a lot of people get pregnant and decide they can turn into garbage disposals."
